To all whom it may concern:

Be it known that I, BENZION KARFIOL, a citizen of the United States, anda resident of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Paper Cutting andEmboss- Figure 1, is an elevation of my device viewed from the side.Fig. 2, is a top view of the same omitting the revolving brush g Fig. 3,is a sectional view taken on the lines 22. Fig. 4, is a sectional viewof the guide roller.

A brace D is secured between the frames A A, preferably secured theretoby bolts, as d and 01 shown on one side in Fig. 1, but not shown on theopposite side. tional view Fig; 3, the holes for these bolts This braceD is provided with an aperture d which forms a way throughout itslength, adapted to receive and carry the bracket d". Shown in Fig; 3.The bracket d is provided at one end with the journal bearing d adaptedto receive the shaft 0 of the die. It rests on the brace D and slides inthe way (1. The bracket d is secured to thebrace D by the screw d nut dand thus may be adjusted to any position on the brace D. It will beunderstood that two of these brackets support the die. They are shown inFig. 2 at d and (i As stated the shaft 0 is journaled in the frame A A.The cylindrical die g is preferably keyed to this shaft, and the journalbearings 01 and d of the brackets 01 and 01 are run upon the shaft 0,and adjusted as close as practical to the ends of the die thus lendingsupport to the shaft on which the die is keyed, when pressure is exertedagainst the die.

The stays E and E are provided with slot throughout their length formingways. I have shown a sectional view thereofin Fig. 3. The brackets e ande are secured to the stay E by the screw e and nut 6 and may be adjustedto any position on the stay E, by movin g the samein the ways thereof.The brack ets e and e are provided with the journal In the secbearings eand c and the ways e and e The shaft Z is journaled in thejournalbearings e and 6, which are adjusted as near as practical to the rollerZ. The roller 6 is journaled in the movable bear-ings e and e which movein the ways a and e. Such movement is controlled .by the screws, 6 e, tocause the roller, e, to bear u pontheroller Z.

6 is a metal bar preferably square, or made so as to present a cuttingor planing edge to It moves in the ways e7 e and its movement iscontrolled by the pressure screws e a which cause the same to bear onthe roller Z.

The stays E and E, and their attachments,

are identical with the exception that in operatin g the apparatus, aswill be hereinafter described, the compression roller, e, and thecutting edge, a are omitted when the brackets are used to carry theembossing roller.

The rollers w and are suitably mounted on, and secured to theirrespective axles, 0c and .2, which are journaled in the brackets e e.The roller 1 is secured to the shaft, 0, and revolves therewith. Theroller y is the die roller, the roller .2 the cutting roller and theroller :0 the matrix or embossing roller.

The die roller is of metal, usually engraved according to a design onits periphery, the die being made to present in certain parts cuttingsurfaces to cut the paper or similar material presented to it, and atother parts to present concave or convex surfaces to emboss or indentthe paper, all according to a predetermined design intended to beimpressed upon the paper.

The cutting surfaces of the die, are a degree elevated above theembossing portions. This is illustrated in the drawings Fig. 4, in whicha section of the die is shown, the parts indicated ast'-i, being thecutting surfaces, and those indicated as j--j are embossing surfaces.

The roller .2 is known as the cutting roller, for the reason that itcooperates with the cutting edges of the die to cut the paper. It has asmooth surface, or periphery, and when brought into contact with the dieroller, en gages the cutting edges which as heretofore recited, are adegree elevated above the embossing portion of the die. The paper ispassed between these rollers and the cutting action is performed.

Heretofore it has been customary to employ as the material of which thecutting roller was made, a soft metal such as lead, or material similarto leather. I may employ in this press, rollers made of any suitablematerial, but I prefer to use for such rollers, as best adapted for thepurpose, the material described and claimed by me in my application forUnited States Letters Patent, dated the 8th day of January, 1894, filedFebruary 12, 1894, Serial No. 499,846, in which I describe a chemicallytreated and compressed paper, or vegetable fiber, for use in thisconnection.

I have shown in my drawings, and described, a roller, e, and a cuttingedge, a intended to bear on the roller ,2 for the purpose of smoothingthe surface thereof, as the same is afiected by the cutting edges of thedie. hen soft metal, such as lead, is employed as the cutting bed, it isnecessary constantly during the operation of the machine, to plane oif,and roll down the surface, in order that the same maybe kept as smoothas possible. The hard metal bar presents to the rollerachisel edge, andis pressed against the same by the screws, 6 e", operating to plane orscrape the surface of the roller as it revolves, but it is not alwaysnecessary however to plane or scrape the cutting roller. Often it issufficient to cause the roller e which is of some hard metal, to bearupon the cutting roller by means of the screws, c, 8 while the cuttingroller is revolving. This operates to smooth the surface of the cuttingroller by pressure. WVhether the cutting edge or roller or both areemployed is dependent upon the material of which the cutting roller ismade and must be determined by a proper adjustm ent of the partsaccordingto the work to be done. I have found that where a roller madeof chemically treated and compressed paper, or vegetable fiber is usedas the cutting bed, it is unnecessary to use the cutting or planing edgea or the compression roller 6. These may, therefore, be omitted in thiscase.

The roller 00 is the matrix or embossing roller. That which has beensaid herein regarding the material employed in the manufacture of thecutting roller is also true of this roller. Lead and other soft metalshave been used, also leather and kindred materials, but I prefer to useas best adapted for the purpose the material described in my saidapplication. The matrix is made by bringing the die roller and a rollerof suitable material into contact under pressure, and revolving the samerepeatedly, until the elevations and depressions of the die arefullyimpressed into the surface of the matrix roller.

It has been my observation and experience with apparatus heretoforeconstructed for the purpose of cutting and embossing paper, that theywere frequently inoperative for the reason that it was impossible intheir construction to adjust the parts to a perfect center, or to bringthe die in such relation to the cutting and embossing rollers as to besuccessfully operative. One of the causes of this difliculty ofadjustment in the apparatus referred to, is the fact that the pressuredirected against the die roller, or the cutting or embossing rollers, asthe case may be, in the operation,

is calculated to bend the shaft or axle upon which they are mounted,thus causing the operation of the machine to be impeded, and the die andits cutting bed, or the die and its matrix to be thrown out of uniformengagement. This is the case for the reason that in ma chinesconstructed for the purpose heretofore, the rollers have been mounted onshafts or axles of a length sufficient to accommodate a die and itsrollers of any length. With this construction the shorter the die andits rollers, the more liable were the shafts and axles to bend, as thepressure thereon was brought nearer the center thereof. To obviate thesedifficulties I have constructed a machine in which the pressure of thecutting roller and matrix roller is directed against the die in oneplane running through the center of the three rollers. Then I haveprovided brackets with journal bearings to carry and sustain the shafton which the die roller is'keyed, said brackets being adjustable so thatthey may sustain the shaft on both sides of the die roller and close tothe same, and act as a brace to the shaft to prevent the same frombending, on the principle that the shorter the shaft the greater itsstrength or power of resistance.

In like manner I have provided adjustable brackets having journalbearings, to carry the axles of the cutting and matrix rollers, intendedto be adjusted to sustain the axle of the rollers, on both sides thereofand close to the rollers. It will be observed that with thisarrangement, whatever may be the Width of the die and other rollers, thebrackets may be adjusted to sustain the'shaft or axles close to therollers, and avoid the danger of the shaft or axies bending, asheretofore recited.

In the drawings, Fig. 1, I have shown a revolving brush 9 which isomitted in Fig. 2 j ournaled in the movable bearings, g, and actuated bythe belt, 9 The position of this brush is determined by the movement ofthe screws,f and f and it is intended to bear on the die rollers andpaperin the operation ofthe machine, and in its revolution to brush awaythe portions of the paper which have been cut out of the paper band asit passes between the die and the cutting roller, in order that suchparticles of the paper may not interfere with the embossing operationbyfilling up the matrix or otherwise.

By the arrangement of adjusting screws, it will be observed that I canbring a high degree of pressure to bear on the cutting and matrixrollers, in directing them against the die, and that I can regulate thispressure to either end of the rollers, so that should there be anyirregularity in the roller, I can compensate for the same by operatingthe screws.

I have so constructed the frame of the device that the die roller is inthe center thereof, and I have formed three ways, or guides, in whichthe stays carrying the rollers and brush may move. I may, therefore,with this arrangement, shift the position of the rollers and brush atwill, that is to say, I may change the places of the matrix roller andbrush, or cutting roller and brush, or matrix or cutting rollers, as Imay find the efficient operation of the machine may require.

The operation of the device is that of passing a band of paper, as Hwound on a spool h, under the guide, if, thence between the dierolleryand cutting roller 2, when these operate to cut the paper; thencebetween the brush, g, and die roller, the brush operating to remove theparticles of paper out out as stated; thence between the matrix roller00 and die roller 1 to perform the embossing of the paper; thence to thespool h Power is conveyed from the pulley, I), through the train to thedie roller, and the cutting and embossing rollers are caused to bear onthe die roller and revolve therewith. The brush, 9 receives its motivepower from the belt,

g but it may, of course, be operated otherwise.

What I claim is 1. In a paper cutting and embossing machine, thecombination with a cylindricaldie suitably journaled, and cutting andembossing rollers, of brackets provided with journal bearings, to carrythe shafts upon which the rollers are mounted said brackets beingsupported by stays having ways in which the brackets are adjustable,according to the length of the axes of the rollers, and said staysworking in ways at right angles to the axis of the die and rollers andmeans to compress said rollers against said die and to adjust saidpressure substantially as described.
